Hi, thanks for help everyone. Now it's much more clear. I downloaded the "Beginner's Guide to the FFT-objects in Pd" from Frank (http://footils.org/pkg/fft-tut.tgz). And have some more questions:
-> working on patch fft-up-close.pd: I have a blocksize=8 and a samplerate=44100 and all analysis have been printed here: orig: 0.13004 0.26951 0.40352 0.52934 0.64446 0.74649 0.83341 0.90344 img: 0 1.0317 0.41678 0.17191 0 0 0 0 re: 4.4602 -0.58717 -0.46243 -0.44167 -0.43735 0 0 0 amp: 4.4602 1.1871 0.62253 0.47395 0.43735 0 0 0 amp-normal: 0.27876 0.074192 0.038908 0.029622 0.027334 0 0 0 after-fft: 0.13004 0.26951 0.40352 0.52934 0.64446 0.74649 0.83341 0.90344 => Ok, with a block of 8 i have data control over 4 partials from the incoming signal rigth? The frequencies are given by multiples of Samplerate/blocksize, starting on F0= 0hz , that's rigth? So, my question is about the normalized amplitudes(amp-normal): 1) Why the first is so loud? This is not the F0 (0 hz)? 2) With the normalized amplitudes i can estimate wich partials are more relevants to the resynthesis (wich partials are more louder in a particular spectrum/audio)? Is this rigth? -> working on "specgate~.pd" 1) My Pd (vanilla 0-40.2, on debian) don't recognize the [>~] object, isn't a native object? Case not where i download this object? thanks for all. cristiano Abra sua conta no Yahoo!
